核电反应堆微型控制网稳定性分析

The analysis of the stability of mini surveying control network in the nuclear reactor site

微型控制网作为核电站各厂房内设备定位的测量基准,应用于核岛土建结构施工和设备安装,是核电站测量控制系统的重要组成部分。在变形监测点稳定性分析中,较常用的方法为平均间隙法及单点假设检验法等。本文提出了结合秩亏自由网平差的拟稳平差方法及圆形控制网网点变形的切向偏差及径向偏差公式对变形监测网点进行稳定性分析。

Mini surveying control network is the datum of plants＇ equipment positioning in the nuclear power＂ station, and it is applied to the civil construction and equipment installation on the nuclear island. So it is an important part of engineering surveying in the nuclear power plant. For the analysis of the point stability for deformation monitoring, the common methods are the method of mean gap, the single point of displacement significance test and so on. This paper presents a new method which combines free network adjustment and quasi-stable adjustment, and gives the formula of tangential and radial deviations.
